Established in 2015, the HEARTs Research Group is an interdisciplinary multi-institution community of race and health scholars–undergraduate and graduate students, postdoctoral scholars and faculty–interrogating relationships between race, racism and mental and physical health outcomes.
The HEARTs Research Group promotes research and scholarship related to understanding why some groups, particularly socially minoritized racial and ethnic groups, live sicker and die sooner than others. Who gets to live longer healthier lives and who doesn’t? HEARTs is guided by several underlying themes: the conceptualization and measurement of racism as a social determinant of health; the embodiment of social stress with a focus on race-related stress, biological dysregulation and premature biological aging; and and the understanding of how race, gender, age and socioeconomic position intersect to impact health inequities.
HEARTs Team Members
Dr. Amani Allen, PhD
Amani M. Allen is Associate Professor of Community Health Sciences and Epidemiology at the University of California, Berkeley, School of Public Health. Her broad research interest is to integrate concepts, theories and methods from epidemiology and the social and biomedical sciences to examine racial inequalities in health as they exist across populations, across place and over the life-course. Dr. Allen considers herself to be more “exposure” than “outcomes” focused, which is consistent with her interests in examining social factors such as “race” and “socioeconomic position” as exposures that serve as the foundation for the creation and preservation of health disparities across a number of outcomes. She is interested in how these social exposures determine life experiences and opportunities differently for different social groups and how those differences become embodied and impact mental and physical health and well being. Dr. Allen’s work employs a mix of quantitative and qualitative data for understanding racial health disparities, informing the measurement of social determinants and addressing concerns related to internal validity challenges in health disparities research. Dr. Allen has published in top scientific journals including the American Journal of Public Health, American Journal of Preventive Medicine, Annals of Epidemiology, Psychoneuroendocrinology–where her paper examining racial discrimination, educational attainment and biological dysregulation among African American women was named Editor’s Choice (2019), and Annals of the New York Academy of Sciences where her recent paper examining racial discrimination, superwoman schema, and allostatic load among African-American women was highlighted as the cover feature. Dr. Allen and her work have been featured on NPR, CBSNews, BlackPress USA, the Urban League, Essence Magazine, US News & World Report, The Guardian, SF Chronicle, The Atlantic, WebMD, CNN, and MSNBC, among others.
